This wikiHow teaches you how to reconnect your mobile device or computer to a wireless network after resetting the network's settings or updating to a new device, as well as how to troubleshoot a connection.

Steps

Method1

On iPhone

1

Open your iPhone's Settings

. This app is typically found on the Home Screen.

2

Tap Wi-Fi. It's near the top of the Settings page.

3

Tap a network's name. This should be the name of the network to which you wish to reconnect.

4

Enter the network's password if prompted. You'll do so in the field that's to the right of the "Password" heading.

If you don't know the password, look for it on the bottom or back of the wireless router or modem.

If you aren't prompted to select a password, your phone should automatically connect to the router.

5

Tap Join. It's in the top-right corner of the screen. As long as your password is correct, your iPhone should reconnect to your wireless router within a few seconds.

Method2

On Android

1

Swipe down from the top of the screen. Doing so will bring down the quick settings menu.

2

Long-press the Wi-Fi icon

. It's generally in the top-left area of the quick settings menu.

3

Tap a network's name. This should be the network to which you wish to reconnect.

4

Enter the network's password. This is either the password you created for the router when you set it up, or the default router password that's on the back or bottom of the router unit.

If you purchased your router and modem together, look for the password (also called a "network" or "security" key) on the back or bottom of the modem as well.

5

Tap CONNECT. As long as the password is correct, doing so will prompt your Android to reconnect to your wireless router.

Method3

On Windows

1

Click

. It's the series of curving lines in the far-right side of the task bar.

You may first have to click the ^ to the left of the volume or battery icon to see the Wi-Fi option.

On Windows 7, the Wi-Fi icon looks like a series of increasingly tall bars.

2

Click your router's network name. If you set up the router with a specific name, it should appear here.

If you didn't set up a specific name, you should see the router's brand (e.g., "Linksys") and model number.

3

Click Connect. It's in the bottom-right side of the Wi-Fi network's name area.

4

Enter the network's password. You'll do this in the text box below the "Enter the network's security key" heading.

If you didn't add a password to your network when setting up the router, the password (called a "Security Key") is on the back or bottom of the router unit.

5

Click Next. As long as the password is correct, your Windows computer will be reconnected to the wireless network.

Method4

On Mac

1

Click

. Click the Wi-Fi icon in the top-right side of the menu bar.

2

Click your router's name. It should appear in the drop-down menu below the Wi-Fi icon. If you assigned a name to your router when setting it up, the name will appear here.

If you didn't use a custom name for your network, you'll likely see the router's brand or model number (for example, you might see "Cisco" and a series of numbers and letters for a Cisco router).

3

Enter the password. This is either the password you created for the router when you set it up, or the default router password that's on the back or bottom of the router unit.

If you purchased your router and modem together, look for the password (also called a "network" or "security" key) on the back or bottom of the modem as well.

4

Click OK. Doing so will reconnect your Mac to the router.

Method5

Troubleshooting

1

Restart your devices. Sometimes a device simply won't connect to a wireless router because of an improper start-up sequence. Restarting your device may fix this problem.

2

Determine why your device won't automatically connect. If your wireless router kicked your device off of the network, it may be because of a few different reasons:

The wireless Internet's password was changed - Select the wireless network and enter the updated password.

The device is not up to date - Update your device to the minimum required version.

The router was reset - Use the router's stock password to connect. The stock password (also known as the "security/network key") is usually on the back or bottom of the router.

3

"Forget" the connection on your device. Causing your computer or phone to "Forget" the Wi-Fi network's settings will clear up any connection conflicts. To do so:

iPhone - Open Settings, tap Wi-Fi, tap a network, and tap Forget This Network at the top of the page.

Reset the router to factory settings. You can do this by finding the "Reset" button, which is usually a tiny hole on the back of the router, and pressing it with a bent paperclip for ten seconds. Once you reset your router, you'll be able to reconnect using the router's stock password and network name.

5

Try connecting to a different network. If you can connect to a coffee shop's or school's Wi-Fi but can't connect to your own, the problem is likely with your router or connection, not your device.

6

Call your service provider's Customer Support hotline. If your router or connection is the problem, you'll need to call and request a network test or a replacement router and modem (if you rent equipment from your ISP).

Community Q&A

Go to the network center on your computer. You can access a simple version at the bottom right of the screen in Windows. The network name should be on a list of available networks -- click on it and then click "connect." If it's not there, it's either out of range or your PC lacks wireless capability.

Is it possible to lose the internet connection on one PC and not the other?

Community Answer

It's possible if something went wrong on that specific computer (or it was deliberately disconnected from the internet). Make sure the computer is not in Airplane Mode and doesn't have the WiFi option turned off.

If you can still read the stock password off of the back of the router, you can reset the router and then reconnect using the stock password. Otherwise, you can call the router's company and request a new password, though you'll likely need the router's serial number.

Tips

If you can't get wireless Internet to work on your computer, try using an Ethernet connection by plugging an Ethernet cable into the "Internet" port on the back of your router and then plugging the other end into your computer's Ethernet port.

Warnings

If your device is too old to receive a wireless signal, you will likely have to update to a newer device.
